On the unit circle, an angle terminates at the coordinate (x,y). What is the relationship between the x and y components of the

coordinate and the trig functions sin and cos?How can we use those relationships to predict the sign (+/-) for these trig functions when an angle terminates within a given quadrant?

The unit circle is represented below:

As can be observed in the figure above, for an angle (t), the relation between the trigonometric functions and x and y components is:

x = cos(t)

y = sen(t)

x is positive in the first and in the fourth quadrant. Thus, cos (t) will be positive for angles in the first and fourth quadrant.

y is positive in the first and in the second quadrant. Thus, sin (t) will be positive for angles in the first and second quadrant.

Solve -3(2x - 9) = -3.<br><br> -4<br> 4<br> -5<br> 5
posledela
-3(2x-9)=-3
We have to solve this equation.
-3(2x-9)=-3
-6x+27=-3
-6x=-3-27
-6x=-30
x=(-30)/(-6)=5

answer: x=5

Suppose the function H(t) = 8.5sin(0.017t – 1.35) + 12 models the hours of sunlight for a town in Alaska, where t = 1 is the fir
Vitek1552 [10]

Answer:

  3.5 to 20.5 hours

Step-by-step explanation:

The range of the sine function is -1 to 1, so the range of H will be ...

  -8.5 +12 = 3.5

to

  8.5 +12 = 20.5

The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.
